Influence of cultivar, fungal exudates fractions and zinniol on cell suspension esterase activity.

Carrot cell suspensions with six different genotypes were tested for esterase specific activity in the presence of fungal extracts and toxins.1ESA is for Esterase Specific Activity, expressed in nmol min−1 mg(prot)−1.2Activities with the same letter are not significantly different. h1 homogeneity groups were obtained by a single ANOVA analysis of all the results followed by LSD multiple comparisons.3Activities with the same letter are not significantly different. h2 homogeneity groups were obtained by a separate ANOVA analysis of the results for each cultivar followed by LSD multiple comparisons.4The treatments were as follows: rA: Alternaria dauci (strain FRA017) fungal culture raw extract; rM: uninoculated medium raw extract; aA: A. dauci fungal culture aqueous extract; aM: uninoculated medium aqueous extract; oA: A. dauci fungal culture organic extract; oM: uninoculated medium organic extract; DMSO: DMSO solution at a concentration corresponding to oM, z1, z2 and z3 treatments; z1: 0.025 µM zinniol; z2: 10 µM zinniol; z3: 500 µM zinniol. C: no treatment.
